Casement windows
For hinged openings. Discuss opening clearance, ventilation, handles and the combination of opening and fixed panes.
Send opening direction, sizes and any screen requirements.

Thermal-break aluminium windows for your project
Discuss thermal-break frame, glazing and opening options with YULUX. Match the proposed configuration to your project requirements and request a quotation. YULUX coordinates manufacture and project support from Foshan, China.
PRODUCT CHOICE
Choose the opening type, then the configuration.
Use these product routes to discuss a thermal-break configuration. The available frame system, glazing and hardware are confirmed for your opening; a product family alone does not establish thermal performance.
Sliding windows
For horizontal opening where a projecting sash would use valuable space. Compare panel layout, usable opening and track details.
Send panel layout, sizes and access requirements.
Explore sliding windows →Sliding doors
For larger glazed access openings. Confirm panel arrangement, threshold, hardware and the proposed sliding mechanism.
Send opening width and height, access needs and threshold constraints.
Explore sliding doors →CONFIGURATION OPTIONS
Put the frame, glass and opening on one specification.
Frame and opening
Discuss the thermal-break frame system, opening layout, dimensions, finish and hardware together. Include clearances and the wall interface.
Glazing and room needs
Discuss insulating glass, Low-E coating and other glazing requirements alongside orientation, shading, daylight and noise priorities. Confirm the complete glass make-up offered.
Targets and evidence
Share the thermal targets supplied by your designer or project team, including the required rating method. Use them to assess the proposed configuration.
For the technical background, read the thermal performance guide. Return with the opening type and project targets to discuss a specific option.
PERFORMANCE DOCUMENTATION
Understanding performance reports
Send your opening schedule and project requirements. We’ll review which performance documents apply to your specific configuration — system, opening type, size and glazing all affect the applicable scope.
Your project team will confirm whether the available documents meet your local requirements. We’ll help you understand which reports we have and what they cover.
Ask about my configuration →Understanding performance values
A glass-only U-value describes the glazing unit; the whole-window U-value includes the frame. Check what each figure describes and which test method was used.
Low-E refers to a glass coating type. Performance values depend on the complete window configuration, not just the product name.

BEFORE YOU COMPARE
See how scope is presented.
Compare quotation scope
Use the supplier comparison guide to line up systems, glazing, hardware, inclusions, exclusions, packaging and trade terms against the same project requirements.
Read the supplier comparison guide →Workshop and packing photos
Review the production and packing photos, then discuss frame protection, labels, handling and loading requirements for your order.
